Background and Objectives Purpose in life is associated with healthier cognitive outcomes in older adulthood. This research examines within-person dynamics between momentary purpose and cognitive function to provide proof of concept that increases in purpose are associated with better cognitive performance. Research Design and Methods Participants (N  = 303; 54% female; M age = 51.71, SD  = 7.32) completed smartphone-based momentary assessments of purpose and short cognitive tasks 3 times a day for 8 days. Results In moments when participants felt more purpose driven than their average, they had faster processing speed (b  = −1.240, SE  = 0.194; p  < .001), independent of person, temporal, and contextual factors and practice effects. Momentary purpose was unrelated to visual working memory performance (b  = −0.001, SE  = 0.001; p  = .475). In contrast to purpose, momentary hedonic affect (e.g. happiness) was unrelated to momentary cognition. Discussion and Implications Feeling more momentary purpose may support faster processing speed in daily life. Such evidence provides stage 0 support for a purpose-based intervention for healthier cognition, which may be particularly useful in middle adulthood and the transition to older adulthood before the onset of cognitive impairment.

Objectives Heterogeneity among Black adults' experiences of discrimination and education quality independently influence cognitive function and sleep, and may also influence the extent to which sleep is related to cognitive function. We investigated the effect of discrimination on the relationship between objective sleep characteristics and cognitive function in older Black adults with varying education quality. Method Cross-sectional analyses include Black participants in the Einstein Aging Study (N  = 104, mean age = 77.2 years, 21% males). Sleep measures were calculated from wrist actigraphy (15.4 ± 1.3 days). Mean ambulatory cognitive function (i.e. spatial working memory, processing speed/visual attention, and short-term memory binding) was assessed with validated smartphone-based cognitive tests (6 daily). A modified Williams Everyday Discrimination Scale measured discriminatory experiences. Linear regression, stratified by reading literacy (an indicator of education quality), was conducted to investigate whether discrimination moderated associations between sleep and ambulatory cognitive function for individuals with varying reading literacy levels. Models controlled for age, income, sleep-disordered breathing, and sex assigned at birth. Results Higher reading literacy was associated with better cognitive performance. For participants with both lower reading literacy and more discriminatory experiences, longer mean sleep time was associated with slower processing speed, and lower sleep quality was associated with worse working memory. Later sleep midpoint and longer nighttime sleep were associated with worse spatial working memory for participants with low reading literacy, independent of their discriminatory experiences. Discussion Sociocultural factors (i.e. discrimination and education quality) can further explain the association between sleep and cognitive functioning and cognitive impairment risk among older Black adults.

Objectives This study explored the association between place-based characteristics (e.g. neighborhood socioeconomic deprivation) and physical health within older Black adults, a critical gap in the literature as identified by the National Institute on Minority Health and Health Disparities. Methods The sample was from Wave 1 data of Baltimore Study of Black Aging: Patterns of Cognitive Aging (N = 450; M age = 68.34). Variables included the area deprivation index (ADI), objective (e.g. average blood pressure) and subjective (e.g. self-rated health) measures of physical health. Multiple linear regression models were conducted controlling for key sociodemographic characteristics. Results Participants reporting better self-rated health and less likely to need help with activities of daily living were significantly more likely to be living in more disadvantaged neighborhoods based on national and state ADI, respectively, even after adjusting for covariates. A significant age and ADI interaction revealed better self-rated health was associated with a more disadvantaged neighborhood particularly for individuals ≤66 years. There was no significant association between ADI and objective physical health measures. Discussion The findings suggest that national- and state-level place-based characteristics should be considered along with individual-level factors, which can enrich the scientific understanding of how neighborhood characteristics relate to varying health indicators among older Black adults.

Objectives This study examined engagement levels across various domains of leisure activities in community-dwelling Black adults (age range = 50–80 years) and variability in daily leisure activity engagement and positive affect (PA; positive emotions or mood) and negative affect (NA; negative emotions or mood). Additionally, we explored whether PA and NA were associated with leisure activity engagement and whether these associations varied by sociodemographics. Methods Fifty adults (78% women; mean education = 11.62 years, standard deviation = 2.4) reported affect and leisure activity engagement over 8 occasions (2–3 weeks). Results Participants averaged 3 leisure activities/day with more engagement in watching television (news), walking, reading, and visiting others. Multilevel models identified significant within-person variation across domains of leisure activity engagement. A significant main effect was observed between daily NA and reduced social activity engagement. A significant interaction between NA and education was further illustrated on those occasions when NA was higher than usual, social and total leisure activity engagement tended to be lower, particularly for adults with ≤10 years of education. A significant interaction between NA and education was observed for entertainment activities. However, results indicated adults with ≥14 years of education, and a mean NA above the sample average, tended to engage in more entertainment activities. Finally, a significant interaction between PA and age was observed indicating adults aged ≥73 had a greater social engagement, particularly when daily PA was heightened. Discussion Results demonstrate within-person changes in the types of leisure engagement among Black adults. Potential factors related to these changes may result from interconnections between affect and demographic factors (age and education). [ABSTRACT FROM AUTHOR]

Objectives The theory of selective survival suggests that possibly around 70–75 years of age, Blacks may display substantive changes in their pattern of cognitive decline. This study examined the age-graded pattern of cognitive decline within older Blacks by describing a trend that characterizes differences in the change of cognitive decline from ages 51.5 to 95.5, and hypothesized that this age-graded pattern is nonlinear. Method Utilizing 2 waves of longitudinal data from the Baltimore Study of Black Aging, this study used multilevel modeling to test whether the interaction between age and the 3-year study period (time between waves) had a positive effect on changes in inductive reasoning, declarative memory, working memory, and perceptual speed. Results A significant positive interaction between age and wave was found for inductive reasoning, demonstrating an age-grade pattern of change/decline in cognitive pattern for Blacks aged 51.5–95.4. Simple slope probing via the Johnson–Neyman Technique suggested that Black adults ~64 years and younger experienced significant decline in inductive reasoning across study time, whereas for those older than 63.71, the decline was nonsignificant. No significant age–wave interactions were found for declarative memory, working memory, or perceptual speed. Discussion Findings suggest a selective survival effect for inductive reasoning ability among Blacks. With decline evident so early, common cognitive intervention programs targeting adults 65+ may come too late for Blacks, signifying the importance and urgency for early health interventions and public policy designed to promote cognitive reserve.

Background: Musculoskeletal pain alters physiological function, which may be evidenced as early as middle age. Previous research has concluded that middle-aged adults are a high-risk group for musculoskeletal pain and report functional limitations similar to older adults. However, few studies have examined the relationships between musculoskeletal pain and physical function, using objective performance measures in a sample of racially and socioeconomically diverse adults. Thus, this study examined musculoskeletal pain in relation to physical function in middle-aged (30-64 years) White and Black adults and investigated whether the relationship varied by sociodemographic characteristics.Methods: This cross-sectional examination incorporated data from the Healthy Aging in Neighborhoods of Diversity across the Life-Span Study. Participants (n = 875) completed measures of musculoskeletal pain and objective measures of physical performance (ie, lower and upper body strength, balance, and gait abnormalities). Physical performance measures were standardized to derive a global measure of physical function as the dependent variable.Results: Approximately, 59% of participants identified at least 1 pain sites (n = 518). Multivariable regression analyses identified significant relationships between greater musculoskeletal pain and poorer physical function (β = -0.07, p = .031), in mid midlife (β = -0.04, p = .041; age 40-54) and late midlife (β = -0.05, p = .027; age 55-64).Conclusions: This study observed that musculoskeletal pain was associated with poorer physical function within a diverse group of middle-aged adults. Future research should longitudinally explore whether chronic musculoskeletal pain identified at younger ages is associated with greater risk for functional limitation and dependence in later life.

Objective The objective of this study was to examine satisfaction, test anxiety, and performance using computer-based cognitive batteries versus a paper-and-pencil neuropsychological battery among older Blacks. Method Self-identified Black adults (n = 87, age range: 55–86; mean education = 14) completed two computer-based tests (CogState and Joggle) and a paper-and-pencil neuropsychological battery. After each battery, participants reported their testing anxiety and satisfaction using the batteries. Descriptive, correlational, and regression analyses compared satisfaction, anxiety, and performance across the batteries. Results Majority of the participants reported more satisfaction with the computer-based (Joggle: 66%; CogState: 77%) than the neuropsychological (52%) battery. Participants also reported less testing anxiety after completing the computer-based batteries than the neuropsychological battery, F (2, 172) = 22.96, p <.001. Older adults' familiarity and comfort level with the computer were not associated with their performance on the computer-based tests (p >.05). Although testing anxiety was not associated with performance across the batteries, age and education quality were uniquely associated with performance on the CogState and neuropsychological batteries. Conclusions Computer-based cognitive batteries appear to be less intimidating than the commonly used paper-and-pencil neuropsychological tests for Black adults. Thus, these cognitive batteries may be useful tools for monitoring older Blacks' cognitive status. [ABSTRACT FROM AUTHOR]

Objectives The present study examined potential sources of intra- and inter-individual differences in older adults' control beliefs using a micro-longitudinal design. Method Older adults (n = 205) ranging in age from 60 to 94 (M = 72.70, SD = 6.72) completed 8 in-person testing sessions within 3 weeks which included assessments of control beliefs (Locus of Control and Perceived Competence), physical health (physical symptoms and sleep self-efficacy), stressors, emotional well-being (Positive Affect and Negative Affect), and cognition (basic cognition tests, everyday cognition, and memory failures). Results Multilevel models indicated that on days when older adults had higher sleep self-efficacy, more positive affect, and less negative affect, they also had more internal locus of control and higher perceived competence. Having stressors on the previous occasion was associated with lower internal locus of control on the subsequent occasion. Physical symptoms, everyday cognition, and memory failures could be predictive of locus of control for some older adults. Discussion Our findings showed the differentiated antecedents of locus of control and perceived competence, the unique role of sleep self-efficacy, positive affect, and negative affect in understanding antecedents of both, as well as the need to study well-being and cognition antecedents of control beliefs in future studies.

Objective The purpose of the current study is to examine the association between subjective memory complaints and sleep (quantity and quality) in African American older adults. Method Participants from the Baltimore Study of Black Aging (BSBA; n = 351; mean age = 71.99) completed a self-report sleep scale, subjective memory complaint scale, global cognitive status measure, and demographic questionnaire. Results Worse overall sleep quality was significantly associated with subjective reports of difficulty recalling the placement of objects, recalling specific facts from reading materials, and worse memory currently compared to the past. Specific sleep parameters (e.g. longer sleep latency and shorter sleep duration) were associated with negative appraisals of participants' ability to do specific tasks involving memory (e.g. difficulty recalling placement of objects). Participants classified as poor sleepers (Pittsburgh Sleep Quality Index [PSQI] total score > 5) were more likely to report worse memory now compared to the past than participants classified as good sleepers (PSQI total score ≤ 5). Conclusions Evaluation of sleep may be warranted when older adults, particularly African Americans, communicate concerns regarding their memory. Insufficient sleep may be a useful marker of acute daytime dysfunction and, perhaps, cognitive decline. Given memory problems are the hallmark of dementia, our findings support further evaluation of whether poor sleep can aid in the diagnosis of cognitive impairment. [ABSTRACT FROM AUTHOR]

In this study, we examined the relationship between within-person blood pressure and cognitive functioning. We conducted an analysis on 36 community-dwelling elderly individuals (age range = 60-87 years). Participants measured their blood pressure and completed cognitive tasks (i.e., the Rey Auditory Verbal Learning Task, the Letter Series test, and the Number Comparison test) twice a day over 60 consecutive days. We observed a significant interaction between within-person change in blood pressure and average blood pressure for the Letter Series test. Individuals with high blood pressure tended to perform poorly, particularly on occasions when their blood pressure level was above their personal average. These results demonstrate that the relationship between blood pressure and cognition at the between-person level and the relationship within each individual should be further explored simultaneously.
